Some teenagers these days are complete idiots, especially boys, in how they treat their fellow female colleagues/partners.
They think they look cool by hurting the girl's reputation and her feelings in this horrible way, but in fact they bring to light their real character/intentions and this should give a BIG WARNING to anyone who interacts with such fools to depart from them and distrust them.
On the same par, another tragedy in the story is that there are other retarded cretins like this that support such disrespectful acts, which makes me really angry and sad about the character of some of the young people of today's society.
